Low Start Flow Flange Type Gas Turbine Type Flow Meter With Lcd Display

Overview

Liquid turbine flow meter consists of two main parts---turbine sensor and display instruments. It has adopted advanced technology and obtains following characteristics: simple structure, light, high accuracy, good repeatability, quick response and easy to install and maintain. Liquid turbine flow meter is widely applied to measuring liquid in sealed tube; not corrosive with stainless steel 1Cr18Ni9Ti,2Cr13, corundum Al2O3 and cemented carbide; with no fiber, particle or other impurity; kinematic viscosity less than 5 × 10-6m2/s in working temperature. When the kinematic viscosity is faster than 5 × 10-6m2/s, needs to calibrate the meter before using. Also it can match with display instrument with special functions to realize quantitative control, excessive alarm etc. In all, it is an ideal choice for low conductive liquid.

Working principle

When gas flows into the flow meter, first it will pass leading liquid with independent movement and speed up. Under the impact of the fluid, the turbine blade is at a certain angle with the flow direction. Then the turbine produces driving torque. After overcoming the resistance torque and friction torque, it starts to rotate. When all torques reach a balance, the rotating velocity becomes stable and this velocity is in linear relationship with the flow rate. Through rotating, the magnets in the blades change the sensor’s magnetic resistance regularly then the both ends of the sensor feel the pulse output, which is proportional to the fluid volume flow. After being amplified, the pulse signal will be send to correction instrument to process together with the pressure and temperature signal measured by the pressure and temperature sensor. Then the meter will show volume flow rate and the total volume.
